The figure presents two cartoon figures (a coach and a scientist). A graph shows that the scientist has tested 17 subjects and concludes a likely positive effect of the intervention. A graph shows that the coach has tried the intervention with 4 athletes (2 positive results, one no result and one negative) and explains the coach will use the intervention with the 2 athletes that responded positively only. The figure concludes by saying the conclusions of the scientist and coach are not necessarily contradictory.
